WHEEL AND AXLE.

Application filed August 20, 1925. Serial N0. 51,402.

This invention relates particularly to such wheels and axles as are used on mine cars and similar railway cars; but it will be seen that this improvement may be otherwise applied.

The object of the invention is to provide improved means for mounting the wheel on the axle and securing the wheel to the axle and to make provision for lubricating the axle and the parts bearing thereon.

In the form shown by the drawings, all the means for holding the wheel against endwise movement on the axle, in either direction, are applied at the end of the axle, means for making engagement between the axle and the inner end of the hub being absent. I

In the accompanying drawings,

Fig. 1 is an elevation of the outer face of a wheel to which my improvement is applied; p I r Fig. 2 is an upright section on the line, 2-2, of Fig. 1'; V

Fig. 3 is a section on the line, 3, 4l3, l, of Fig. 2, looking toward the right;

Fig. l is a section on the line, 3, 4c3, l, of Fig, 2, looking toward the left;

F 5 is'a horizontal'section on the line, 55, of Fig. 2;

Fig. 6 is a horizontal section on the line, 66, of Fig; 2; V

Fig. 7 is an upright, transverse section on the line 7-7, of Fig. 2; I

Fig. 8 is a perspective of one of the keys;

Fig. 9 is an oblique section on the line, 99, of Fig. 1, looking in the direction of the arrow; 1 i 7 Figs. 10 and 11' are detail views illustrating other shapes of the hub walls to engage the keys; M

Fig. 12is an elevation of'a disc placed at the end of the axle;

Fig. 13 is a vie w looking at the edge of said disc Referring to said drawings, A is an axle of ordinary form and having at its outer end a circumferential channel, A to, receive keys,D. f

B is a wheel having 'a'hub, B surrounding the axle; As an integralpart of the hub, an end. wall, Bi'extends' across the end of the axle and has its inner face positioned to bear against the disc, F, as herein described. The part of thehub surrounding the axle adjacent the end Wall at each side of the channel. A is contracted to nearly meet. the surface of the axle. From said contracted part of the outer end of the hub, the hub is extended to make room for a tubular lining, C, and anti-friction rollers, C bearing on the axle and having at each end a small journal, C At the outer (right hand) ends of these rollers, the hub has an annular channel, B into which the adjacent journals, C extend. At the inner end of the hub a ring, C is fitted against the inner face of the hub and secured to the hub by means of rivets'or screws, C Said ring has a transverse flange, C, extending toward the axle. On the inner part of said flange is another flange, C, turned toward the outer end of the huband serving to engage the adjacent journal, 0 when the wheel and hub are re moved from'the axle. At the same time, the journals, G at the outer-ends of the rollers, 0 are engaged by the flange or lip, B forming the inner wall of the channel, B Thus the wheel and hub may be removed rrom the axle without displacing the rollers from the hub.

In the transverse plane cutting the annular channel, A of the axle, the hub is provided with radial apertures, 13 into which are placed keys, D. The drawings show two such apertures placed diametrically opposite each other. At the outer side of each aperture, 3", and at the outer face of the hub, the aperture, B5, is extended laterally (toward the end wall, B to form a recess, B. heouter end of each key, D, has a lateral extension, D Each key extends into one of the apertures, B the extension, D resting in the recess, 13, whereby the movement of the key toward the axle or into the channel, A is limited. The length of the key is limited so as to. prevent the inner end of the key from making contact with the neck of the axle formed by forming the channel, A This is for the purpose of preventing the keys from wearlng the axle neck to a smaller diameter.

It will be understoodthat such wearing would weaken said neck. The inner end of each key is curved to conform approximately tov the curvature of they axle neck. The part of 'thehub, B ,at each side of the plane cutting the apertures, B is tapering or oblique to resemble a truncated cone. At the outer end of said slanting face is an annular face or shoulder, B in a plane to which the axle is perpendicular. Between said shoulder and the end wall, B the hub has a cylindrical part, B".

The outer ends of the keys, D, are provided with slanting faces, D which are even with the slanting face, B of the hub when the keys are in the working position. A cap, E, surrounds the part, B, of the hub and has a flange, E parallel to the face or shoulder, B The main part of said cap extends over the oblique face, B of the hub and bears against said face and lies over the outer ends, D of the keys, D. Four cap screws, E extend through apertures, E formed in said cap and into the adjacent wall of the hub. Between the flange, E and the shoulder, B is an annular packing, E which serves to prevent the outward passing of lubricant and to prevent the inward moving of dust and dirt. Under the other edge of the cap, E, a circumferential channel, B is formed on the outer face of the hub. Said channel receives packii g, E to prevent outward movement of lul cant and inward movementof dust and dirt.

Fig. 10 shows the part, D of the key omitted and the outer end of each aperture, B is made wider in the transverse plane of the axle, and the outer parts of the keys are correspondingly widened. By this means the tapering keys are held by the slanting faces of the apertures, whereby the keys are prevented from bearing on the neck of the axle in the channel, A

In Fig. ll, the parts are the same as in Fig. 10, excepting that another face in the apertiu'e is made slanting for supporting the key away from the axle neck.

Between the end wall, 1%, and the end of the axle is a disc, F, which serves as a buffer between said walls and the axle when there is end thrust. Said disc is chilled to make it hard and adapted to endure wear. The face which makes contact with the axle is preferably made slightly convex as shown by the drawing. On the axial line of the hub the wall, B has a port, B, for the introduction of lubricant. The face of the disc, l which meets the wall, B is provided with channels, P, which extend from the middle of the disc to its periphery. At the outer ends of the channels, 1 the disc has notches, 2 These channels and notches allow flow of lubricant from the port, 13 to the axle, and thence around the axle to and around the rollers, C Any suitableiclosing plug or similar device (not shown) may be placed intothe port, B.

In order that the hub end wall, B may press the disc, F, against the end of the axle, the channel, A is to be wide enough to allow slight movement of the keys parallel to the axle.
